IMPLEMENT FOR BINDING SHIPPING PACKAGES.

Original application filed February 18, 1921, Serial No 446,034. Divided and this application filed July 25, 1922. Serial No. 577,369.

To all whom it may concern:

Be it known that I, SPENCER CONE CARY, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings and State of New York, have invented a certain new and useful Implement for Binding Shipping Packages, of which the following is a specification.

This invention is an implement for applying a binder under tension to a shipping package of one form or another, usually a box, crate or shook.

The present application is a division, or a continuation, of a prior application filed by me on February 18, 1921, Serial No. 446,034.

The object of the invention is to apply a binder, usually a wire, under tension to an article or package, and to prevent said binder from slipping with respect to a retaining means or gripping means when tension is a plied.

Accor ing to the invention, a wire binder is used, said wire binder being provided with a shoulder of one form or another, and during the operation of applying tension to said binder, the shoulder thereof retains said binder in position relatively to the tensioning implement and to the package. The shoulder on the wire resists the tendency of said wire to pull out of position during the operation 'of applying tension to saidtwvire in order for wire under tension to compress the components of the package, it being essential that the wire shall be stretched into tight engagement with the walls of the package; in fact, the tension imparted to said wire binder is such as to embed said wire into the material of the package at the corners thereof, as a result of which the wire is retained against displacement upon the package and it is not necessary to use staples or other fixtures for holding the said wire against pulling oif the package, particularly in case the wooden walls of the package should shrink after the application of the binder.

A shoulder is provided on the binder at a'suitable oint and, in one-embodiment of the invention, two shoulders are provided at separate points on the wire, the said shoulders performing the function primarily of precluding the wire duringthe stretching a binder.

operation from displacement with respect to the tensioning means.

In carrying my invention into practice, I employ tensioning means embodying a recessed member and co-operable with a wire binder shouldered at its point of grasp by said means, and in one embodiment of the invention the tensioning means comprises a plurality of members and means for effecting a relative movement between said members,said tensioning means being associated with means for locking together the end portions of the binder.

Other functions and advantages of the invention will appear from the followin description taken in connection with the rawings, wherein Figure 1 is a plan view of the implement in position for placing initial tension upon a Figure 2 is a side elevation of Figure 1. LI Figure 3 is a vertical cross section in a plane intermediate the twistin mechanism and one of the stretching and gripping heads F lgure 4 is an elevation partly in section of the twisting mechanism.

Figure 5 is a detail vertical section on the line 5-5 of Figure 3.

Figure 6 is a detail section of one of the gri pers.

igure 7 is a plan view of the shouldered wire with the end portions in lapping relation, said View showing the wire in a condition for looking or twisting together the end portions after tension shall have been placed on the Wire.

One embodiment of means for placing tension initially on a wire binder. is a stretcher comprisingv a plurality of heads A, B, a double threaded screw spindle C, a guide stem D, a locating element E, and grippers F F carried by the heads A B, respectively. Each head A or B is a single casting provided with a threaded aperture a and with a slot (1 above the jaw b, said slot extendin through the head as shown in Figure 6 or the binder to enter the slot freely. The stem D passes loosely through the heads A B near the ends opposite the slotted jaws, said stem co-operating with the screw spindle in keeping the two heads in parallel relation. The guide stem D occupies a fixed relation to the slidable heads A B and to the rotary screw spindle, for which purpose the stem is fitted in an opening of the locating member E and is secured fixedly thereto in a suitable way, as by the cross pin 6. Said locating member is provided with a face plate 6 in depending relation to the body portion of said member E, whereby the face plate is adapted to rest into contact with a side of theshipping package when the implement rests upon the top of said package, see Figure 2, and to thus act as means for locating said implement in-a desired operative relation to the package for the application of the binder thereto. The body portion of the locating member is provided with an opening 6 see dotted lines in Figures 1 and 2, through which loosely passes the screw spindle C, and to one end of said spindle is attached suitable means, such as the crank 0, for imparting rotary motion to said spindle. The spindle is provided with threads of opposite hand, said threads being of coarse pitch for imparting quick action to the spindle, and said threaded parts of the spindle are screwed into the threaded openings at of the heads A B, respectively, whereby the rotary motion of the screw journaled in the opening 6 of the 10- cating member acts to impart sliding movement to the heads A B, the two heads being shifted simultaneously and in opposite directions to each other.

Each head A or B is slotted or forked by the provision of a recess f above the slot a, and within this recess is positioned the cam shaped head f of one gripper F or F, see

Figure 6. As shown, each gripper comprises a cam shaped head f and a handle F. The head f of each gripper is provided with a rib 9, whereas the jaw b of the head is provided with a groove 9, see Figures 2 and 6, the rib g and the groove 9 being in the same plane. The ribbed cam head co-acts with thegrooved underlying plate for crimping the wire binders, thus resulting in the formation of a shoulder. As shown, the two grippers act to produceshoulders at separated points on the wire binder, and these shouldered parts of the binder co-operate with tensioning means to preclude said wire binder from displacement or slipping under the strain applied to said wire in applying the desired tension thereto. A cross pin h passes through the recessed upper part f of the head A or B and through the head f of the gripper, said pin in operating to pivotally attach the gripper to the sliding head and to serve as the fulcrum for the gripper.

The twisting mechanism is positioned for operation upon the crossing end portions of the binder and at a point intermediate the sliding heads A B and their associated grippers F F. As shown, the operating parts of the twister are mounted in or carried by a non-sliding head composed of complemental parts G G assembled into lateral contact with each other and secured firmly together, as by bolts 71/. The twister head is perforated for the passage through it of the guide stem and the screw spindle C, and said twister head is held against sliding movement by a binding screw k mounted in'the rear part of the head and binding against the guide spindle, see Figures 3 and 4, whereby the twister head is fixedly retained in position intermediate the sliding heads A B and grippers F F.

The operating elements of the twisting mechanism consist of a slotted gear H, a master gear l, and an intermediate gear J, said train of gears being encased within the twister head and each gear being mounted in said head independently of the other gears of said train. The twister head is provided at its bottom edge with a jaw and with a slot in above said jaw, said slot extending at one end through an edge of the twister head, see Figure 4c, and dotted lines in Figure 3, in order that the crossing end portions of the binder may be received freely within the slotted part of the nonmovable twister head. The complemental parts G G of the twister head are provided with interior recesses m in the plane of the slot 76 to produce a bearing for the cylindrical body of the twister l'l, whereby said twister gear is mounted for axial rotation within the twister head, see Figures 4 and 5.

The body of the twister gear is provided with a longitudinal slot n, and in the normal position of the twister gear H the slot n thereof is in register or alinement with the slot is of the twister head, thus making provision for the free entry of the crossed portions of the binder into the slot of the twister head and into the slot of the rotatory twister gear, see Figure 4.

The intermediate gear J is supported by a stub shaft j in appropriate bearings within the twister head so that said intermediate gear is in mesh with the teeth of the twister gear H and with the teeth of the master gear I. Said master gear is on a shaft 2? mounted in bearings provided in the complemental parts G G of the twister head, and to this shaft there is secured an operating lever I by a pin 2", said lever I being movable back and forth so as to apply power to the master gear, the movement of which master gear I is multiplied by the intermedi ate gear J for imparting the required rotative movement to the slotted twister gear H by a single movement of the lever I in one direction. 7

' For retaining the crossing or lapping end portions of the binder within the slot is of the twister head and the slot at of the twister gear, and to preclude said crossing binder ends from being thrown out of the twister gear by the rotatory motion thereof, I proraaroee vide retainers, one at each side of the twister head, as shown at O P. Each retainer consists of an arm or plate positioned in close relation to one face of the twister head so as to extend across the slot is therein prior to imparting the rotary motion to the twister gear and at the period of rotation of the gear, but subsequently to the rotation of said gear, the retainers are shifted out of position, for which purpose the two retainers are mounted on a cross pin 0, the latter bein journaled in the twister, head at a point pre erably above the gear H. As shown in Figure 5, .the retainers are fitted on square portions of the cross pin and attached fixedly thereto by screws 0, so that rocking movement of the cross pin imparts swinging motion to the two retainers simultaneously. The retainer may have any desired form, but as shown in Figure 3 one retainer is provided with a lip p and with a finger piece p, the latter affording convenient means for moving the retainer and rotating the-cross pin so that the two retainers are shifted into and out of position by the rotative movement of the cross pin.

Having described the construction of the implement, the operation may be set forth as follows :-The implement is usually placed upon the top of a shipping package indicated at X, with the face plate 6 of the locating member E in contact with a side of, the package, and a binder, usually a wire Y, is looped around said package, the end portions 3 3/ of the binder wire being in lapping or crossing relation, see Figures 1 and 7. The grippers F F being in the opened (raised) positions (see Figure 6), one end g of the wire is passed in the slot a and between the jaw b of head A and the gripper F, whereas the other end portion of the binder is received in the slot a" and between the jaw b of head B and gripper F, see Figures 1 and 2, the overlapping portions y 3 of the wire passing loosely or freely within the slots is, n, of the twister head G G and the twister gear H,,respectively. The grippers F F are now turned for the ribs 9 thereof to crimp or bend the wire toward the'grooves g in the jaws of the respective heads A B, and thus shoulders 00 are formed on the wire at separated points, see Figures 2 and 7 one shoulder on at the head A and the other shoulder ac at the head B, said shouldered points being separated relatively to the twisting mechanism.. The shoulder or shoulders provided on the wire cooperate with one element, or with both elements of the tensioning means, said shoulder of the wire and the element or elements (Jo-operating to retain the wire against dlsplacement or movement With respect to said element or elements of the tensioning means during the operation of placing tension on said Wire. The operator now turns the crank c to rotate screw C, the latter acting to impart sliding movement to the heads A B for drawing them toward each other and toward the twisting mechanism. The operation imposes strain upon the major length of the wire by drawing the same in two directions around the shippingpackage X, whereby the required tension is initially placed upon the wire.

The next step consists in the operation of the twister, but prior thereto the operator imparts movement to the cross pin 0 for moving the retainers U P across the ends of the slot 79 in the twister head, so as to preclude the free ends of the binder from being thrown out of the head by the rotative movement of the twister gear H.

Now, while the binder is held under tension by the heads A B and screw C, the operator moves the lever I in a forward direction, thus rotating gears J T and imparting rotative motion to the twister gear H the latter acting to twist together the lapping or crossing end portions y 3 of the binder.

During the twisting operation, the lapping portions of the Wire are retained within the slot n of the gear H by the retainers O P, and this gear is turned the required number oi times .for completing the twist by a single motion of lever l[, at the end of whichv the gear H is in a position for the slot at therein to register with the slot 70' of the twister head. The retainers O P are now lifted by applying pressure to the finger piece 29, and the grippers F F are released from contact with the binder after which the implement is bodily shifted out of position relatively to the binder under tension, the slots a k permitting the lateral withdrawal of the implement relatively to the binder.
